Unfortunately poisoning is really only a craft skill on this shard. There's been a lot of changes to try and make it worth something in pvp, but it never took. Take everyone else's advice and don't do poisoning unless you want to be able to DP weapons, in that case stick it on your crafter char and GM alchemy while you're working it and turn that into an alchy/stun or alchy/dexxer.
It sucks but it is what it is gl

gonna have to disagree 100%. poisoning isnt good on a mage but on a dexer it doubles your chances to apply the poison, plus you can reapply poison in combat. your initial poison charges are probably gonna trade with your opponents cure pots, so just one application is not gonna cut it.
Reapplying poison mid-fight sounds like it would be pretty useful, but honestly I've only ever seen it happen 2 or 3 times out of 100's of fights. Maybe my experience has been different than yours, but I think 100 skill points are better spent elsewhere. Trust me, I want nothing more than for poisoning to be as viable as a skill such as alchemy, but I just don't feel it is.
